   Plumbline Report — design system

   Direction: surveying instruments, not newsprint. A plumb line hangs
   still; movement is what you measure against it. The vertical line is
   the organising device throughout.

   Palette is drawn from a plumb bob and a drafting sheet: blued steel,
   cool chalk white, brass, verdigris. Deliberately cool where the
   obvious choice would be warm cream.
